Default Block ID

I have a 929 block number in my truck. Is this a good block compared to a 599 block and what are the differences?

Just one of the many castings they used.

The 599 was a non squirt, large outer main bolt block found in the 94 era rigs.

The early 506 was a POS as was the later version.. The early squirt blocks with large squirt nozzles.

Not seen too many 929 blocks

IIRC the 929 block is a 6.2 with the one piece rear main.

These should be a good block, butttttttttttttttttttt... check the center main webs near the outer bolts for cracks.

Easy way is to clean the webs off well with brakekleen and then warm them with a propane torch until the area around the outer bolts is hot.

Any cracks will show a BLACK oil streak down the crack.

The 929 blocks may have been used to do both 6.2 and 6.5 engines.

THE OVERLAP time from 92-93 saw some odd things.

6.2 was available through 1993 as an N/A only.

The block is identical except the bore size.

929 is identical to the late model version of the 599. There is a 92-93 '599 and a 1994 599, the biggest difference was the size of the oil filter and oil cooler bypass valves in the block under the oil filter. Probably changed the identification to 929 to reflect the small change and to avoid confusion with 599's that could be either 6.2 or 6.5 depending on year...

929 was 1995 specific block, so that's likely the original engine and always a 6.5L.

Next year in 1996 it was a 141 to incorporate castings for the center mount turbo (pedestals on all blocks whether used or not).

Then in 1997 and on they're all 506, have to watch the Julian date on the block to tell how late, earlier ones like Robyn mentioned aren't very good.

Not very good is an understatement
